Reverse Design of a Dual-Band Microstrip Patch Antenna Based on Binary Particle Swarm Optimization

$A$
compact dual-band microstrip patch antenna operating at 2.18 and 2.45 GHz is proposed in this paper. The patch area of the antenna is discretized into small squares of the same size, and the binary particle swarm optimization (BPSO) algorithm is used to search for the optimal arrangement of these squares. Compared with traditional patch antenna design method, the proposed intelligent algorithm-assisted design method saves optimization time and provides distinct antenna performance.
